>Description:

	[ may be duplicate of diffrent pr, but it seem to have got lost ]

	put some load on the wi0 card by running network filesystem
	regression test, it seem to end up in OACTIVE (and that is
	usually fixed with ifconfig down/up), so I checked for that with
	ifconfig wi0, this make wi0 unhappy and crash on me.

>How-To-Repeat:
